Fix some errors, including:
- Build fix when WITH_VMWARE_GTK is set.
- Reorder pkg-plist so that @unexec vmware-guestd.sh successfully done.
- Create directories for server modules, since xserver may not be installed.
Even though this makes no "installed" content change, but bump
PORTREVISION since pkg-plist/pkg-plist.tools are changed.
